Top Screen has multiple issues.

Earlier my 3DS was involved in a rather unfortunate soda accident, and after cleaning it out and letting it dry for awhile it works relatively fine, but with a few issues

-Top screen is brighter than bottom and is unaffected by brightness changes in theme menu

-Top screen remains lit while in sleep mode while the bottom screen sleeps like it should

-Error message is given whenever I attempt to use exterior cameras

-3D mode had to be manually disabled via parental controls because the slider stopped functioning (remained lit despite my turning it completely down)

This is an original 3DS, not an XL.

Thank you in advance!
